SELF-CONTAINED TIME-CONTROLLED OPERATING MECHANISM.

Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Self-Contained Time- Controlled Operating Mechanism;

' and I do hereby declare-the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description ofthe same, and which .said drawings constitutepart of this application, and represent,.ini Figure l a View in front elevation of one form which my improved self-contained time-controlled operating-mechanism may assume. Fig. 2 a plan view thereof. Fig. 3 a view of the mechanism in rear elevation, with its several levers in the positions due to them preparatory to'being set. Fig. 4 a corresponding view showin the levers in the positions due to them a ter they have been set and during the operation of the timingmechanism proper. Fig. 5 a reverse plan view of the device. Fig. 6 a View in Vertical section on the line ab of Fig. 4. Fig. 7 a detached view of the timing-disk. Fig. 8 a detached plan view of the timing-lever.

My invention relates to an improved selfcontained time-controlled operating-mechanism adapted to be used in a variety of situations where it is desired to perform an operation at the end of a predetermined period, such as in apparatus for automatic cooking by gas, oil or electricity, in water heaters, in japanning ovens, etc., the object being to produce a compact, convenient and reliable apparatus organized with particular reference to being easily adapted for use and readily removable in use.

With these ends in view, my invention 1 consists in a self-contained time-controlled operating-mechanism having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a, setting-lever 2 provided at its lower end with a handle 3, furnished at its upper end with an index-pointer 4- and formed, near its upper end with a square opening 5 receiving a sguare shoulder 6 upon the hub 6* of a timmgisk 6", mounted upon the front end of a-main or winding arbor 7 Specification of Letters Patent.

to which the said lever is secured by a cap nut 8. The'said index-pointer 4 sweeps over a graduated dial 9 formedupon a dial-plate 10 located directly in front of the main frame 11 of the apparatus, the saidframe being made of heavy sheet metal. The arbor 7. is journaled in the front and rear movement-plates 12 and 13 of a timingmechanism which may be of any approved construction, the said plates being held together by ordinary movement pillars 14. A coiled spring 15'mounted upon the rear end of the arbor 7 is wound b the rotation thereof in counter-clockwise irection by the setting lever 2, and when wound drives the train of the timing-mechanism, the said train being sufliciently indicated for the present purpose (Figs. 3 and 4) by means of the main wheel 16, the pinion. 17, the wheel 18, and the balance-wheel 19. At its forward end, the arbor mounts the timing-disk 6 rigidly secured to it, and formed with a' timing-notch 21 receiving a tooth 22 formed upon the adjacent edge of a vertically arranged timing-lever 23 hung at its upper end upon a stud 24 in the frame 11, the said tooth 22 riding upon the periphery of the disk 6". The swinging movement of the lever 23 on the stud 24 is guided and limited by the passage of its lower end between guide-plates 25, 26, secured by screws 27, 28, to the frame 11. A helical tripping spring 29 attached at its upper end to the arm 30 of the lever 23 and at its lower end to the screw 28, exercisesv a constant effort to hold the edge of the tooth 22 against the periphery of the timing-disk 6 and also effects the entrance of the said tooth into the said notch when the notch is brought into registration with the said tooth by the clockwise rotation of the disk 6, due to the unwinding of the spring 15. The said lever 23 is also formed with a lifting-arm 31 co-acting with a latcharm 32 forming an extension of an operating-lever 33 mounted, as shown, upon a short shaft 34 the ends of which are journaled in two depending lugs or arms 35 formed integral with the main frame 11. The latcharm 32 is formed with a nose 36 entering a notch 37 in the outer edge of the timinglever 23 which is thus adapted to maintain the operating-lever '33 in its set position against the tension of the main or powerspring 38 which is attached at one end to a lug 39 on the said arm 33, and at its other end to a stud 40 in the frame 11. The shaft 34 also carries a coupling-arm 41 from which the coupling-rod 42depends, the said rod 42 constituting, as it were, the coupling-member of my improved mechanism. In the par-- ticular, mechanism shown, the rod 42 is formed at its lower end with a dovetail 43 for coaction with a corresponding dovetail 44 at the upper end of a connecting rod 45, the dovetails 43 and 44 being held together by means of a sleeve 46, but the particular fofm of the coupling-member 42 may, of

course, be widelyvaried.

' As shown, the winding-arbor is ,pro-

vided with a friction device 47 whereby it is frictionally connected with the main-wheel 1641s more fully shown and described in the co-pending application of Joseph W. Gibney, filed Feb. 4, 1915, Serial No. 6148. The said arbor 7 is thus frictionally coupled with a member of the esca'pement-train, whereby the setting-lever 2 may be operated to unwind the main or power spring 15after the mechanism-has been initially set. This permits'the time-limit to which the device Was initially set to be reduced to any desired extent or nullified altogether. I do not however limit myself to the use of friction I "coupling-means of the character described.

In the operation of my improved mechanism, the operating-handle 33 is first pulled down against the tension of the power spring 38 so as to cause the lifting-arm 32 to oothe tooth 22 from reentering the notch 21, until after the setting-lever 2 has been graduation upon the dial 9'will, of course,

be determined by, and conformed to, the character of the use. The movement of the lever 2 from left to right will also effect the winding of the main or power spring '15. The handle 33 must be held down to keep moved enough to carry the said notch out of registration with the tooth which thereafter rides upon the periphery of the disk,

v vwhereby the said lever 23 is held in position for the-engagement of the nose 36 of the latch-arm 32 with the shoulder at the bottom of the notch 37 in "the said lever, all this being necessary to hold the -coupling-rod 42 in; its elevated position against the tension of the power sprin 38 which is energized .by the' depr 'on o the operating-lever 33.

the driving-spring 15 thereof will slowly turn the timing-disk 6 in the clockwise direction until the expiration of the-time-limit to which the device was set, when the notch 21 will be brought into registration with the tooth 22 at which time the tripping-spring 29 will act to swing the timing-lever 23 from right to left for the entrance of the tooth 22 into the notch 21 and the disengagementof theshoulder of the notch 37 from the nose 36 which will release the shaft 34 to the action of the power-spring 38 which will now be rocked and positively ef- "fect the depression of the coupling-rod 42 are connected.

I call particular attention to the self-contained character of my improved apparatus which adapts it as a unitary organization, to be applied to and readily removed from the apparatus or device which it is desired to control on the basis of a predetermined time-limit. If any change is necessary in adapting-my mechanism to the apparatus to be controlled, the change will be practically confinedto the coupling-member 42. I particularly wish to point out that in my apparatus, the operating-lever supplying the power is organized as a part of the apparatus so as to wait with the timing-lever which in turn co-acts with the timing-mechanism. I have shown no housing, but it will be understood that, if desired, the entire mechanism may be inclosed in a case ofany suitable description.

I claim:

In a self-contained, time-controlled opcrating-mechanism, the combination with a timing-mechanism including a setting-lever and a timing-disk, of a timing-lever co-acting withthe said disk, an operating-lever co-acting with the said timing-lever, and a coupling member connected with the .said operating-lever, the said parts being combinedin a unitary structure adapted as such to be applied and removed to the mechanism to be operatedby it. f
